To all whom 'it mayponcem:

Be it known that I, MERLE WESLEY MIL- LER, a citizen of the United States, residing at /Varren, in the county of ,Warren and State of Pennsylvania, have inventedcertain new and useful Improvements in Gages, of which the following is a specification.

This invention relates to gages.

The object of the invention is to provide a simple and inexpensive implement by the use of which the correct measurements and markings preparatory to cutting mortises for the face plates of locks, strike plates, etc., may be made with greater facility than by the use of implements as heretofore made, thereby effecting a material saving of time and labor.

With this object in viewthe invention consists of an implement 'having the generic and specific features of form and relative arrangement of the parts substantially as hereinafter described and claimed.

The invention is illustrated in the accompanying drawing in which;

Figure l is a face view of the gage; Fig. 2 is an end elevation; and, Fig. 3 is a side elevation particularly showing a flange formingpart of the gage.

Thegage maybe made of wood, metal or other suitable material, preferably of sheet metal. It consists essentially of a body or plate 1 having extending from one edge thereof a portion 2 which increases in width from its point of juncture with the other part of the body, and has the sides thereof stepped. The main portion of the imple-" ment has in it a slot or opening3 of a suitable width and having the sides thereofv parallel with the edge of the plate 1. Extending from the body 1 of the plate at each end at a right angle thereto are arms 4.

All the parts are marked on their faces near their edges with graduations preferably indicating inches and fractions thereof. The plate 1 on each side of the opening 3, therein has on it marks indicating distances from the outer edges of the arms 4, the markings on the opposite sides of the slot being the reverse of each other, adapting it for ready reading with either of the arms 4 elevated thus permitting the use of the implement on the right or left hand side of a door, jamb or the like to be measured and marked. Each arm has on it graduations or marks indicating in inches and fracisindicated by t-ions thereof the distances .from the edge of the plate 1 toward the ends of the arms.

tween the plate or body 1 and thearms 2,

at each'end of the implement are openings 5 which are triangular in general form, each having one side thereof parallel to the outer edge of the plate 1, and having another side at right angles to the edge ofthe plate 1. The-other sldes of the openings are formed by steps the depths and lengths of which indicate respectively distances from the edge of the plate 1 and from the outer face of the arm 4 adjacent to which the opening is located.

Formed with the edge of the plate 1 and bent at a right angle thereto 15 a flange 6 the edge of which is provided with a series of rectangular openings or indentations .7. The indentations increase in depths from one end of the flange'to the other in predetermined ratio. .For instance the depth of the first indentation may be '3 of an inch,

the depth of the next one of an inch, the

next and so on. Any number of these indentations may be employed, there being four shown in the present illustration.

In the use of the implement, for instance for marking a door jamb to indicate the lines on which to out to form mortise for a butt, it is placed against the jamb with the flange 6 pressed against the edge of the jamb to bring it parallel thereto, and the arms 4 are brought against the face of the pamb. A line drawn across the face with the outer edge of the upper arm4 as a guide will give a line for the upper end of the mortise. The location of the lower end of the mortise introducing a marker through the slot and making a mark in accordance with the scale adjacent thereto, the plate being moved down if required to give the length. The width of the mortise is indicated by placing a pencil, knife or the like into the notch on the part 2 which indicates the distance the inner edge of the a .butt is to be located from the edge of the jamb, and the implement is then drawn downward while theflange is maintained in contact with theedge of the jamb.- The depth of the mortise is indicated by placing a markin implement in the proper opening or in entation in the flange and moving the tool along the edge of the jamb.

roceeding as in marking the first line. v A' ine indicating the center of the mortise at which boring 1s to be done, .may quickly and accurately be determined and indicated by the use of the proper notch in the upper face of the portion 2. v I

In marking for a mortise for a strike 1 plate a marker is placed against one of the notches of the face of one of the openings 5 and the implement moved a roper distance, to indicate the outer ge of the mortise, and the other parts of such mortise are indicated in the manner heretofore described.

Having thus described my invention, what I claim as new, and desire to secure by Let-' 'ters. Patent, is

1. A gage consistingof a body one edge of which consists .ofa tapering stepped por-' tion, the other edge .belng formed with a; flange extending ata" right angle to the.

face of the body, and-arms extending from the body at right angles to the flange,

'2. A gage consisting of a body having a longitudinal slot therein, and having a ta ering stepped portion at one edge thereof? the other edge being formed with a flfflnie extending at a right an le to the face 0 t body at right angles to the flange.

3. A gage consistin of a'body having a longitudinal slot thereln, characters indicatin graduations, the reverse of each other, adfiacent to the slot, a tapering stepped portion extending at one edge of the body, the other edge being formed with a flange .ex tending at arightangle to the face of the body, and arms extending from the body at right angles to the flange.

4. A gage consisting of a body having a tapering stepped portion at one edge thereof, the other edge being formed with a flange extending at a right angle to the face ofthe body and having openings or indentations of varying depths in the edge thereof, and armsextending from the body at right angles to the flange.

5. A gage consisting of a body having a tapering stepped portion at one edge thereof, the other edge being formed with a flange extending therefrom at a right angle to the face of the body,'arms extending from the ends of the body at right angles to the flange, and an opening in the body adjacent to the juncture of each arm with the body, one side. of each 0 ening being provided with notches the si es whereof are parallel respectively with the flange and with the ,outer faces of they arms.

In testimony whereof I afiix my signature in presence of two witnesses.
